Data can also be referred to as raw facts, it’s meant to be processed into meaningful information that can be used in decision making by organizations. Data metamorphosis into information after it has been passed through several data analytical processes.
Examples of data: names of students in a class, results of an experiment, GDP of different countries in Europe, heights of students, BMI of patients, tweets, list of students in a faculty, videos uploaded on YouTube, audio files uploaded on sportify, etc.
Data is everywhere, data is being generated in every sector but there’s a difference in how data is being harnessed into information in different sectors.

Search engines use search history, location data etc to come up with search results and adverts.
E-commerce businesses use purchase history data, search
